The "divine elixir" answered all questions.
However, when Fang Jinyu heard it, his expression became a little more serious.
It was because, according to the pill spirit, "Yao Zaixian" came from the immortal realm and was an immortal above the immortal Almighty, who ranked 9 in the Immortal Ascension stage! Later on, he participated in the "Rebellion of the Hundred Immortals" and was removed from the immortal records, banished to the "Boundless Realm," where he could never return.
The "Boundless Realm" was a place of punishment in the immortal realm. Even immortals were afraid of it.
The "divine elixir", or elixir spirit, was one of the few trump cards that "Yao Zaixian" had left behind with his avatar before he was exiled.
